Set of 40 hex, star and spline bits made from Alloy Steel. Includes two Chrome Vanadium sockets.

All of the bits, with the exception of a few of the larger bits, share the same 12mm diameter hex base, which allows faster bit changes.

Each bit has its size imprinted on the bit itself, making it easy to identify them after you've removed a handful from the case. And to make tidying up quicker, the case displays the bit sizes next to each housing.
